Table 26-3. DID Field Descriptions
Description
Part Revision Number. Contains the revision number of the part. This field changes with each revision
of the device or module.
Design center.
Part identification number. Contains the part number of the device.
Manufacturer identity code. Contains the reduced Joint Electron Device Engineering Council (JEDEC)
ID: 0x20.
Fixed Per JTAG 1149.1. Always set to 1.
26.6.2.2 Port Configuration Register (PCR)
The PCR is used to select the NPC mode of operation, enable MCKO and select the MCKO frequency,
and enable or disable MCKO gating. This register should be configured as soon as the NDI is enabled.
The PCR register may be rewritten by the debug tool subsequent to the enabling of the NPC for low power
debug support. In this case, the debug tool may set and clear the LP_DBG_EN, SLEEP_SYNC, and
STOP_SYNC bits, but must preserve the original state of the remaining bits in the register.
NOTE
The mode or clock division must not be modified after MCKO has been
enabled. Changing the mode or clock division while MCKO is enabled can
produce unpredictable results.
